Abstract

PURPOSE:To make big end bearings around upper and lower adjacent crank pins lubricated constantly and unfailingly by providing an oil supply chamber above the said adjacent crank pins. CONSTITUTION:When an engine is run, an oil pump 38 is driven, feeding lubricant oil to an upper oil supply chamber 40 and a lower oil supply chamber 41 through an oil feed path 39. The oil fed to the chamber 40 is supplied to big end bearings 26 around a first crank pin 22 and a second crank pin 23 through a main oil supply path 42 and branch oil supply paths 43 and 44. The oil fed to the chamber 41 is supplied to the big end bearings 26 around a third crank pin 24 and a fourth crank pin 25 through a main oil supply path 45 and branch oil supply paths 46 and 47. Namely, by thus utilizing the space separated from crank chambers by a sealing 28 as upper and lower oil supply chambers 40 and 41, constant lubrication can be ensured without needing to provide complicated oil supply paths to a crank case 12 and a crank shaft 13.

法が提案されている。Two-stroke engines are often used in outboard motors.In two-stroke engines, the load acting on the big end bearing is extremely large, so it is necessary to reliably lubricate this part. Therefore, in conventional two-stroke engines, in addition to the lubricating oil supply line that supplies the mixture with the fuel to the crank chamber, the lubricating oil pumped through the lubricating bong is connected to the big end bearing. A method has been proposed to make it possible to supply

り不光分となる。However, in the previously proposed method, lubricating oil is first supplied to the main shaft and bearing of the crankshaft, and after lubricating the main bearing, the large end bearing is lubricated by the lubricating oil flowing down. Therefore, the required amount of lubricating oil is not necessarily supplied to the big end bearing. In particular, when the crankshaft has a plurality of adjacent crankbins between the main bearings, the lubrication of the big end bearing formed around the lower crankbin becomes more difficult.
